SPECIFICATION forming part of Letters :Patent No. 18,027, dated January 6, 1903.l

Application filed May 14, 1902. Serial No. 107.356. (No model.)

VTo @ZZ whom, t mfagyiconccrn.:

Be it known that I, MATHEW E. ROTHBERG, a citizen of the United States, and a resident of Lebanon, in the county of Lebanon and State of Pennsylvania, have made a certain new and useful Inventionin Coke-Ovens; and 1 declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of `this specication.

Figure l is a half longitudinal section through a main system of heating-lines and a half-longitudinal section through an oven. Fig. 2 shows vertical sectional views taken on the lines A A and B B, Fig. l, and also shows an end view of oven and iiue. Fig. 3 shows sections taken on the lines C C, D D, E E, and F F, Fig. l.

The invention relates to horizontal openend coke-ovens; and it consists in the novel construction and combinations of parts, as hereinafter set forth.

The object of the invention isto provide such ovens with a system of heating or combustion lines whereby it is designed to secure great economy olf-heat, strength of construction, and rapidity of coking action. The invention is also designed to provide efficiently for regulating and distributing the heat in the different iiues, thereby affording means for heating the diierent parts of the ovenwall at will, and, further, the invention contemplates means for imparting the heat from the waste gases to the air-supply.

The nature of the invention will be clearly understood in connection with the drawings illustrating the same, in which the letter Z designates the coking-chambersof the cokeovens, and J the hollow wall between the coking-chambers.

T represents the top of the ovens, and F the hollow or flue bottom.

The ovens are built in adjacent pairs, asindicated, and the hollow wall between the coking-charnbers has its cavity separated into two compartments by a vertical partition D, extending transversely. Each of these compartments is traversed by a vertical reverting-flue consisting of a series of horizontal combustion-dues or heating-hues B, formed by horizontal deflecting-partitions b b, one above another, such fines B communicating at alternate endsl in series by the short vertical passage lues e e next the partition-Wall D and e e next the face-wall G of the oven. The lower end of each vertical series of lines B communicates, by means of the angular flue f, with a horizontal series ot' transverse reverting-fines C, which extend under the oven-chamber, being in the bottom F. This series of transverse reverting-dues at its outer end communicates with the longitudinal horizontal reverting-line N, which is under the hollow wall J in the bottom portion of the oven. The transverse reverting fines are formed in the hollow bottom by the transverse detlecting-partitions c c, in connection with the longitudinal walls fm of said bottom, and the longitudinal horizontal reverting-flue N is formed by the long deiiecting-partition a.

At or near the termination ot the longitudinal Ii ue Nin the bottom is provided an opening g for the connection of the valved passageor pipe l, which extends to the air pipe or ue L, which branches from the hot-air chamber M, which extends around the drafttiue P, through which the waste gases pass to the stack. The pipe lis provided with a regulating-valve 2. j

The detlecting-partitions b b of the vertical reverting-flue in the hollow wall J are alternately joined to the central partition D and to the face-wall G of the oven. In those which are joined to the face-wall G are provided near such junction in the line of the series of the short fines e e with the valved passages 3. By means of these passages the tlues B can be short-circuited, so that the products of combustion can be made to pass directly from one flue B to the next without traversing the length of the iiue. The valves are indicated at 4.

The outer ends of each series of revertinglues C are providedwith an opening 5 through the face-wall for the pipe 6 of the fuel-gas main S, said pipe having a regulating-valve.

The heated gases 'pass through tion-dues and air-fines the oven-chambers are encompassed in such wise that their heating can be quickly accomplished and easily regulated to suit the work.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

l. In adjacent coke-ovens, a hollow bottom, partitions in the cavity of said bottom and forming transverse reverting combustioniiues, a hollow Wall separating the oven-chambers, a transverse partition dividing the cavity of said wall into two compartments, partitions forming longitudinal reverting combustion-ues in said compartments, a reverting hot-air flue leading to said transverse filles, a draft-flue above the ovens, a hot-air chamber surrounding the draft-flue, and supplying hot air to said hot-air flue, said longitudinal combustion-fines communicating below with said transverse nues, and above with the draft-Hue, substantially as specified.

2. In adjacent coke-ovens, a hollow bottom, partitions in the cavity of said bottom and forming transverse reverting combustioniiues, a hollow wall separating the oven-chambers, a transverse partition dividing the cavity ot said Wall into two compartments, partitions forming longitudinal reverting combustion-nues in said compartments, a reverting hot-air flue leading to said transverse flues, a horizontal draft-flue, a hot-air chamber surrounding said draft-flue, a hot-air pipe communicating with said reverting hotair flue, and with said hot-air chamber, said longitudinal combustion-fines communicating at one end thereof with said transverse iiues, and at the other end thereof, with the draft-flue, substantially as specified.

In testimony whereof I affix my signature in presence of two Witnesses.
